Abstract: 761,435. Gas turbine plant. BRISTOL AEROPLANE CO., Ltd. Jan. 29, 1954 [Feb. 17, 1953], No. 4469/53. Class 110 (3). In a gas turbine engine having hollow inlet guide vanes in the air intake of the engine, means (other than hollow rotor shafting of the engine) are provided to convey air tapped from a compressor of the engine to the interior of the guide vanes, thereby heating them, and then into heat exchange relation with a part of the engine requiring cooling. In the engine shown, the intake 14 of the air compressor 37 is disposed between the compressor and the turbine 38. Air tapped from the compressor is led through the duct 11 to an annular manifold 12a, the wall 14a of which constitutes the outer wall of the air intake. Hollow air intake guide vanes 16 are mounted in a ring 13 and communicate with the manifold 12a through apertures 15a. The inner ends of the vanes are mounted in an annular manifold 18 and the air passes therefrom through apertures 19 into two pipes 20 which communicate at their downstream ends with an annular chamber 36. Air issues from the chamber 36 through apertures 139, some air flowing over the upstream face 35 of the turbine rotor disc 24, and the remaining air passing through passages 25 into a recess 28 from which it passes through passages 29 and over the faces 39 and 40 of the rotor discs 24 and 30. Some air also flows from the recess 28 across the downstream face of the rotor disc 30. The air streams after flowing across the rotor faces enter the main gas stream flowing through the turbine.

Title: Improvements in or relating to electric distance protective arrangements
IPC: H02H3/40
Filed: 1945-02-22
Abstract: 585,516. Protective cut-out arrangements. REYROLLE & CO., Ltd., A., and JOHNSTONE, W. G. Feb. 22, 1945, No. 4512. [Class 38 (v)] In a distance protective arrangement for polyphase circuits, a compensating current is injected into the current windings of an earth-fault measuring apparatus to compensate for the error in measurement due to the division of fault current between the earth return path and the healthy phases. The star-connected current windings H'-H' of an interphase-fault measuring apparatus are energized from the delta-connected secondary windings F<1>-F<3> of auxiliary transformers, each having three primary windings, one primary winding from each auxiliary transformer being connected together in series, and in series with one of the star connected secondary windings B'-B' of main current transformers in the phase conductors A<1>-A<3> of the circuit to be protected, e.g., C<1>, D<2>, E', are connected in series with B<1>. The current windings G<1>-G<3> of the earth-fault measuring apparatus are connected in series respectively with the individual secondary windings F<1>-F<3>. The second and third sets of primary windings on the auxiliary transformers are arranged to inject current into the earth-fault measuring device to give the desired compensation for earth faults. The compensation may alternatively be obtained by injecting a current derived from the residual current circuit, Fig. 2 (not shown). In this case the auxiliary transformers each have two primary windings, the first set being connected in star and in series with the secondary windings of the main current transformers. The second set is connected in series in the residual current circuit between the star point of the first set and the star point of the main current transformers. In other respects the circuit is similar to that illustrated in Fig. 1. In both cases the interphase and earth fault relays have the same ohmic setting and are arranged to operate substantially simultaneously for all faults within a predetermined distance therefrom. Specification 474,768 is referred to.
